The world's biggest freeskiing and snowboarding competition returns to Aspen for another weekend of history-making events.

Extreme sports fans will travel to Aspen's Buttermilk Mountain to watch some of the world's best extreme athletes pull off breathtaking stunts. Here are a few things to know for those attending their first X games or some fresh info for X Games vets.

X Games Aspen will feature men’s and women’s ski and snowboard competitions in Superpipe, Slopestyle, Big Air, Knuckle Huck, and Street Style.

The X Games will experiment judging halfpipe runs this week in Aspen using artificial intelligence, the cutting-edge technology that could someday play a role in the way subjectively judged sports are scored.
